SAFETY DEVICE FOR BOX-ENDING- MACHINES.

To all whom it may concern:

Bev it known that L'W LLIAM BRA-NDSTAED- run, a citizen of the United States, residing at Hanovenin the county of York and State of Pennsylvania, have invented anew and use in connection with box enders wherein the operator holds the paper box body on a former block while the former and the header are finishing the ends of the box. In such instances the fingers of the operator hold the sides of the box to the side of the former block and the thumbs hold the bottom of the box to the front of the block and therefore the hands are necessarily exposed to the.

danger of being caught between the former block and the header.

The object of thepresent invention is to preventthis by providing the former block with guards that will prevent the fingers from being caught between the header and former block and which will push the fingers out of the way of danger.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings :-Figure 1 is a front View broken away showing the safety attachment in position. Fig. 2 is a side view of the former block showing the attachment. Fig. 3 is a top plan View of theformer block, and Fig. 4 is a detail view of the safety 7 device.

header of usual construction, and B' the former block of ordinary construction. Secured on each side of the former block are the plates or blocks 1 towhich are secured the flat spring members 2 and to the opposite ends of the flat spring members are secured the safety devices or guards 3 which are pro vided on the ends with the right angle extensions 4;. As is clearly'shown in Figs. 2 and 4 of the drawings the guard members 3 areof such a shape that it extends upward from the flat spring members 2 and as shown in Fig. '2 engagesthe header A' at all times.

Applicant is aware that it is not broadly new to provide a guard fora machinev of this character butwhat he claims as new is a guard resiliently connected to the former block and held in such a position that it will engage theheader at all times. It will be seen that it will be impossible to place the fingers between the header and former block as the guards '3- extend above the top of the Y former block and the right angle extension 4 will prevent the thumbs being placed in such position as to be caught between the header and former block. In machines of this character the former block reciprocates and moves toward the header. It will therefore be seen that when the former block is raised in. my device the guard 3 will be forced downward and should the fingers be in any danger they will be pushed downward with the guard. 1

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is In a forming machine, the combination with a header, and a movable former block, of finger guards yieldably connectedtothe sides of the block at a point below the upper edge of the block'and extending upwardly at an angle so that the free ends extend above the top of the block, and said finger guards having extensions extending in front of the block. I

In testimony that I claim the foregoing ture in the presence of two witnesses.
